Node Protection Card

 

Optical Bypass Protection Card for Node Protection, Bi-directional protection in SMF, 1RU Rack Chassis

Node protection is a intelligent optical switch system which can bypass fault node in optical transmission network to avoid breakdown of whole network communication. It can automatically switch by detecting the nodes optical power or signal failure. Therefore to ensure that traffic from an LSP traversing a neighboring router can continue to reach its destination even if the neighboring router fails.
Fiber-Mart’s FM-OBP-C is a node protection card. It can be installed into FM-P-OTP800 series transport platform for more capacity solution in limited environment. The FM-OBP-C will bypass the unpowered switch and simply pass network traffic to the next switch in the relay. It is widely used in PDH, SDH, C/DWDM, power communication and CATV systems for optical monitoring.
Key Features

  • 1:1, 1+1 and 1-1 protection for optional
  • Less than 15ms automatic switch time
  • Real-time monitoring nodes from nodes failure
  • It uses the insert plate structural design of Mini 0.5U, which is convenient for installation
  • The switching module is designed with simple and stable circuit, which is with high reliability
  • Supports multiple management modes such as Console, SNMP as well as button assignment
  • Supports synchronous communication of voice alarm and network management system
  • Supports Fast, Gigabit and 10 Gigabit Ethernet fiber connections in SC/ST/FC/LC connectors
  • The main equipment at receiving site have three modes for switching: automatic, forced manual and remote control
  • Designed with excellent heat dissipation and temperature adaptability, it can be applied in various complicated environments

  • Front Panel Appearance



  • Console: Interface for the serial command line management

  • Auto/Force: Auto/Forced-mode switch button

  • Primary/Secondary: Click to select the primary or the secondary path under the manual mode.

  • Optical interface introduction: There are 8 optical interfaces on the device’s control panel: T1, R1, T2, R2, T3, R3, T4 and R4.

Application Case

Protection Illustration


It shows an example of how you can implement node protection based on 1:1 protection operation. The 1:1 protection adopts 2x2 optical switch technologies. In default mode, the Tx signal towards the main line, through SDH/ADM node equipment, and the selector chooses the Rx traffic from the main line. When the middle node failure, the network will bypass the failured node and automatically switch to backup line.

It shows an example of how you can implement node protection based on 1+1 protection operation. In 1+1 operation, a splitter bridge sends the Tx signal to both line (the main line and the backup line) and a 2x1 selector switch selects the signal from one of the line. In default mode, traffic from the main line is selected. In this illustration, SDH/ADM act as an node between two transmission equipment. When the power failures, the selector near the Rx side of the failed traffic detects the failure, switches over, and selects the traffic from the backup line.
